lh INIPROVED -UIMBRELIAA The Schedule referred t infthese Letters Patrt and making part lof the same.

To all fit mwy concern VBe it k'nown that I, .Icons MoAULmFE, of the city, county, and State of'New York, have invented a new and usefullmprovement `in Umbrellas; 'and do here# by declare that the following is a full and exact de`` scription thereof', reference being had to the accompa'f 4nying drawings, making part of this specification, of

which- Figure 1 is a plan, or top view; Figure' 2, a sectional elevation Figure 3, a frontview-of `o ne'of vthe ribs removed' from the' frame; .and

Figure ,4, a'sidefelevation of saidrib.

This invention, relating to -an improvement in me tallic-fiamed umbrellas, consists insucl construction and arrangement of `-parts thereof as will secure the desired qualities of lightness, elasticity, and durability use ofthe same weight of material; audit further" consists in attaching to said rib, near its centre, a lap for the reception of the bifurcated end of the stretcher, l

' end of each rib works in a notch 1n the grooved crownplate, and is embraced' by a ring in said groove pass-- which lap operates measurably in the manner of a bellcrank, reducingthe friction in the usual joints at this place, permittingqa curving movement,`and thus removing the strain from. the joints in the crown-plate, the drangement of which is so frequent, and sd diiiicult to repair.

rIt will he observed also that by the use, of the lap, or intermediate' connection betweenthespreader and the rib, strength is imparted to the rib, that is to say, at the point of greatest strain, and where the ribs of urnbrellas are usually weakened by perforations', and the l spreaders by flattening.

What I claim, and desire to secure 'by- Letters A indicates the metallic frame of the umbrella. f IB B, Src., the ribs.

C C, the stretchers,.or braces, which are fastened at one end to the runner I), in the ordinary manner, and to the ribs by their bifurcated ends E, embracing the laps G,said laps being 'pressed on 'the ribs, as aforesaid; and l H H are' the loop-ends of the ribs, connected with the upper notch I, asalready-explained and shown in the drawings. f v

I am aware that in umbrellas heretofore made, the

upper ends of the ribs form hooks, which are held in place in the top'notch by'a crown-piece; and 1 am aware that umbrellas have been made with the connec'tions of all the parts formed of loops in the wire; 4but y those-Ilay no claim to, the former being inoperative, and the latter forming a knuckle-joint at the -points of 'connection of the ribs and .stretchers, the .ribs

fI'n testimony whereof, I have hereunto set my .sigf
